Microsoft has released Build 14393 of Windows 10 Anniversary Update for PCs and Mobile devices in Fast Ring for Windows Insider testers. No words till yet, whether this is the RTM build or not.
The announcement has been made from Dona Sarkar at the Windows Blog. Because there is no information about the RTM state of the build, I guess, that Build 14400 may be the RTM.
This build includes only a few new fixes, because Microsoft is close to RTM, I guess. For the PC version, Microsoft has:
- improved the reliability of Start, Cortana, and Action Center
- mounting an iPods as USB mass-storage devices should work now
To my surprise, “improving” the start menu and Cortana once again indicates to me, that those features the weakness of Windows 10. I haven’t read such an announcement during Windows 7 beta tests.
For mobile devices, Microsoft also announced a couple of fixes, which surprises me. Here are the details:
- They fixed an issue resulting in rapid battery drain when Visual Voicemail syncs voicemail messages on Dual SIM devices like the Lumia 950 XL.
- Microsoft also fixed an issue causing some battery drain on older devices like the Lumia 535, 640, 735, 830, 930 and Icon.
- They fixed the issue causing Voice Recorder to not show up consistently as an option for Call Recording. A app update was released last Friday that fixes this issue. Make sure you have the app version 10.1607.1931.0.
- And Microsoft fixed several issues impacting Dual SIM capabilities. Using a device with two SIMs should work as it should.
But there are still known issues …
The fact, that Surface Book and Surface Pro 4 may stall with a blue screen in Build 14393 surprises me. Microsoft will fix that issue with an update delivered via Windows Update. Microsoft lists the following known issues for mobile devices:
- They are continuing to investigate W-Fi issues on certain devices.
- Turning off Bluetooth can sometimes result in freeze, crash, or reset (see here).
- Wallet users are prompted for a PIN twice when using tap to pay from a locked phone. You can enter their PIN twice and tap as usual once the phone is unlocked. A fix for this will come as a Wallet app update via the Store.
There is also a reminder. Microsoft has changed the backup format for Windows 10 Mobile devices to reduce the size of the backup stored in OneDrive. As a result, if you do a backup on a device running the latest Windows 10 Mobile Insider Preview builds and move back to the released version of Windows 10 Mobile (Build 10586) and restore from your backup – your Start screen layout won’t restore and remain the default Start layout. Your previous backup also gets overwritten. If you need to go back to Build 10586 temporarily, once you are on Build 10586 you should disable backup so it doesn’t overwrite the good backup from Windows 10 Mobile Insider Preview builds. Microsoft will stop noting this going forward.
